All aboard the Magic School Bus! The enchanted vehicle pulls up for a second go-around with a frizzy-haired teacher behind the wheel in the Netflix reboot-sequel of the beloved PBS animated series. In The Magic School Bus Rides Again, the teacher is a little less frizzy-haired, though she’s still a Frizzle.

That’s right, that’s Kate McKinnon as Ms. Frizzle’s younger sister with better hair, Ms. Fiona Felicity Frizzle, taking the keys from Lilly Tomlin‘s legendary teacher as the older Frizzle goes off to…save the world, I guess? But the most important thing about The Magic School Bus Rides Again trailer is that Netflix has recruited Lin-Manuel Miranda to sing the updated theme song. Yep, that definitely made our day complete.
